The hate against spring on hacker news is so ridiculous. Spring boot is one of the easiest lowest boilerplate ways to build anything, period. Especially if you use a type dynamic language on top, like groovy or kotlin or whatever.
Some people are just masochistic or they just want to distract themselves by solving problems that have already been solved by Spring circa 10 years ago. Most of them don't even use the technology that they preach around here, it's borderline trolling.
